}

Use assert.NoError(t, err) to more strongly assert conditions than just assert.Nil.

Not so sure why you convert the bytes.Buffer to a bytes.Reader when it’s already an io.Reader.

@puellanivis thanks, i think i make typo, today i found more correct solution:

import "google.golang.org/protobuf/encoding/protojson"

protojson.Marshal(m proto.Message) ([]byte, error)
protojson.Unmarshal(b []byte, m proto.Message) error
